(CNN) - Luci Baines Johnson was just 16 years old when she approached her father, President Johnson, with what she considered a reasonable request.

"I asked my father if we could have the Beatles come to play at the White House," she recalled. "I was very excited about it."

His response? A decisive no, "without even any moment of trying to soften the blow," Johnson said in a recent phone interview.

The president thought the move would be viewed as self-serving. His daughter, however, saw it as a chance to honor "a great talent" and strengthen ties between the United States and Great Britain - not to mention a golden opportunity for her and her friends.

His son, Rand Paul, announced this week he's set his sights on the Kentucky Senate seat being vacated by retiring Republican Sen. Jim Bunning.

"I'm very worried about our country; I'm worried about the debt. I'm worried about what the debt will lead to," Paul told CNN when asked why he's jumping into the political arena. "Both sides of the aisle - Republican and Democrat - have been unwilling and afraid to address the deficit, and someone's got to."

(CNN) - President Obama on Friday reiterated his commitment to passing comprehensive immigration reform, telling a Hispanic audience that the country must be guided by the principle "love thy neighbor as thy self."

"The American people believe in immigration, but they also believe that we can't tolerate a situation where people come to the United States in violation of the law," Obama said before the eighth annual National Hispanic Prayer Breakfast in Washington.

"Nor can we tolerate employers who exploit undocumented workers in order to bring down wages," he told the crowd at the breakfast, which was sponsored by Esperanza, the largest Hispanic faith-based evangelical network in the country.

Obama said the "fair, practical and promising way forward" is by strengthening border security, clarifying the status of those who are here illegally, and requiring illegal immigrants to pay a penalty and taxes, learn English and go to the back of the line for citizenship.
